(Part 1 of 2) Richard Heinberg is Senior Fellow-in-Residence at the Post Carbon Institute and has written extensively on energy, economic, and ecological issues, including oil depletion. His talk on Our Renewable Future is set among all the frightening news about accelerating climate change. However his message is serious but positive. He asks: How will our daily life change as we fully embrace the era of renewable energy? How will we need to shift the ways we use energy – offering both opportunities and challenges?
